概括

与草交叉种植狼可以显著减少土壤蒸发,提高用水效率. 这种系统改善了土壤水分动态,增加了植物的透气,在干旱地区提供了节水的好处.

科学领域:

农业科学农业科学
土壤科学土壤科学
水文学的水文学

背景情况:

交叉作物系统下的土壤-植物-大气连续 (SPAC) 动态,特别是关于土壤蒸发,水分和透气的动态,需要进一步阐明.
狼 (Lycium barbarum L.) 和 (Medicago sativa L.) 的交叉种植为干旱地区的可持续农业提供了潜在的战略.

研究的目的:

为了研究狼-草交叉种植对土壤蒸发,土壤水分动态和各种灌制度下的作物透气的影响.
量化节水的好处,并了解干旱环境中交叉作物的潜在机制.

主要方法:

在两年内进行了实地实验,比较单独种植的狼 (D) 与狼-柳交叉种植 (J).
使用SIMDualKc模型在四个灌水平下进行模拟:完全 (W1),轻微赤字 (W2),中度赤字 (W3) 和严重赤字 (W4).
测量包括土壤蒸发,不同深度的土壤水分含量 (SWC) 和植物透气.

主要成果:

与单独种植 (DW1) 相比,间隔种植 (JW1) 将年度平均土壤蒸发量减少了32%.
与完全灌 (W1) 相比,缺水灌水平 (W2-W4) 显著降低了土壤蒸发.
间作物导致根区 (0-60厘米) 的土壤含水量降低 (7-19%),植物透气量增加29%,表明水的吸收和利用效率提高.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
